This article explains bicarbonate of soda (baking soda) mouth rinses and sprays.

• They help with a dry mouth and when the mouth is too acidic.

Bought rinse

1. Use about 30 ml (1 to 2 capfuls).
2. Rinse for about 30 seconds.
3. Spit it out. Do not swallow.
4. Do this 3 to 4 times a day.

Home-made rinse

• If the mouth is very sore (for example during cancer treatment or with very dry mouth): mix 1/4 teaspoon of bicarbonate of soda and 1/4 teaspoon of salt in 1 cup of warm water.
• After treatment is over: use 1/2 teaspoon instead.
• Swish it around the mouth and spit it out. Then rinse with plain water.
